Application l'ed Fchruaryil, 1920. Serial No. 359,600.

To all whom t may] concern.'

Be it known that l, Josnrri WALTER BARRY, a citizen of the UnitedStates,residing at Everett, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Cocks,"of

which the following is afspecilication'.

This invention relates to So-called, ball.

cocks, controllingv t-he ingress and egress of water to. and fromflushing tanks, or other ,y receptacles, the liquid-controlling valve.of`

the cock being opened by the descent4 of a float supported by. a bodyvofwater in 1 the tank, and connected with a lever which comvalve.

' Inunicates motion `Afrom :the float' toffthe One object/of theinvention is to provide an improved constructionof thelle'ver and float,providing for a. quick and secure de tacha-ble 'connection between thelever and iioat, which is preferably of glass', thus avoidingcomplicated, tedious, and expensive connecting means, such' asarepresentedby;Vv

a toggle bolt"withits attendant check nuts,

Other objects of the inventiony are to provide improvements vrelatingtocertain details of the structure disclosed by my Patentk No. 925,153,dated June 15, 1909.

The invention is embodied' in ,-thei'mi provementswhichl will nowproceed to describe and claim. f f zk f l f the accompanying rawingsforming a; part of this Specication,.-

- Figure 1 is a sectional view of a portion .of a flushing tank anda'ball cock embodying I y "meansof a flanged'stud `31,'forn1ed,` ont-hematerial v,Olffthe' my invention, applied thereto, thecock-be-kingmainly shown in section, and the Yfloat being .Shownmainly inelevation and the toggle coupling hereinafter described,being shown inside elevation. A Figure 2 is asideview, showing the stu forming theouter endof the longer arm of i the lever, and anv edge view of thetoggle casing having ,a chamber which contains the 'vided with "atransverse inner side of thefhead.4

. stopper, as shown by Figure Y 32 represents a hollowv` float,` whichvis stopper.

sphericalvalve 16, n ormallyheldl by fluid pressure against avalveseat17 the ca-sing i 14 being provided with an inlet branch '18. 20represents the dischargetube, which has a sliding` lit in theportion-'of the casing 14, below .the valve seat, said-:tubel having afinger 21, adapted to tip orrollthe spherical valve 16, all as setdescribed. y f v As before, the tube 20 opens'the valve when itisraised-by the'downward Inove-l ment of a iioat lever,gand it descends byits own weight, to permit the. valve, to close when the float leverrises.y y l Thel ioat'lever has two arms of unequal length,'and iscomposedof a hub portion 22, connected by ya fulcrnm lpin 23, with xedears'24, on the casingla, said hub having a forth in the patentabove n lcam projection 25 at one l'sidfeof the-'fulcrum i constituting ltheyShorter arm ofthe f lever. The hub hasuaninternally threaded socket 26,projecting from the opposite', side of the fulcrum, and constituting jan inner.- member of the longer arm of the lever. aScrew-threadedshankengaged with the'4 Socket 26, land, constitutinganfouter `mem-4 ber of thelonger arrnlof., the. lever.;.. Said 27vrepresents l so y studv is providedwith ar-rigid, and preferablycircular head 28 fat its Outer end, the-head.

and VStud being preferablyhformed in 'one piece,-fas"a casting, and thestudbeing;pro-l 3() represents- ,a compressibleVVV stopper, which .maybe of elasticrubber, and is rmly.: securedr yto lthe l head28,.-'preferably by headV and embedded inthe ,orifice 29`r at, the f 3lneferablyspherical, and is provided with a, v suitably elongatedtubular-neck 33,said float n and neck being preferably made' ofqglass.j

The neck is formed to.v receive andlbe1 se-` curely`l closed by thestopper' 30, Itheinouth loo ofthe neck bearing 'on theflange 30a oftheThe floatneck'is detach-ablyjsecured to the,

f lever by means yof aAtogg'le-coupling.' if One element of saidcoupling isv al substantially f r UTShaped lever member 34, havinginwardly i projecting trunnions 35 `at its koppositeends, adapted toturn-in sockets formedby conf volutions of a wire band`3v6, surroundingllo,

theneck 83. l

The lever Betis provided with loops or eyes 37,` forming sockets 'atopposite sides ofthe neck and adjacent to the sockets 36. rl`he toggle,coupling also includes a substantially U-'shaped 'tension member 38,the neck portion ol'which passes loosely through the stud orifice 29, sothat the tension memberv BScooperates with the lever in coniining themouth otthekneckagainst the stopper, and maintaining'thefstopper undercompression between the float neck andthe head 28, this being thecondition that prevails whenfthe toggle is active? /Vhen thetoggle isrenderediiinactive, or is broken by swinging the leverimemberl outwardtronifthe positionshown'by Figure 2,' the rbottle leck is permitted torecede from -thestoppen and is detachable therefrom.

lt Awill bei seen thatthe head Q8, the stopperf,'-andthetoggle'coupl-ing above described, constitute` a'well known tornrotbott-le stopper which l have adapted tor use in'faiioat leverfby rigidlyconnecting` the studf'Z- :to the head portion of` an ordinary bottlestopper;v so that-the stopper is rigidly connectedv with* theportionotthe longer arml ofthe lever formed Vby the shank. The operation of Vthetog'gle lcoupling moves thef'tioatneclrltoward and from the' stopper,instead ot'moving'fthe stoppertoward and from? the neck, as isthe oasein a bottle stppery lt willbeseeny by reference to Figure l,thfatftliestud 27 is'in'elined relatively to the head 28, `se thatthelongitudinal axis ot the stud is inclined relatively to thevlongitudinala-Xis of theneclr and tloatl.V This arrangement permitsavariation of the h'eight'otfth'e float, by turning `the shank 27 inlthe socket 26'. The shank'is provided wit-ha lo'clr nut Q7, to preventitsy accidental rotation.

The-shorter' arm- 25 ot the lever bears on a screwpost 40, attached tothe tube 20, so that-'when Ythe float descend-stile tube 2O iseraisedto\fopen"th'e valve 16 by means' of the fingerQl.' v v The tube 20'is'provided below the screwpost l0 with an adjustable stop, whichlimits' the downward movement of the float, and is composed of' 'ascrew-threaded stud 'l-l, en-y gaged withtappedforiiices in*Y oppositesides of thetubeQO," and 4provided 'at one side ot conveniently turnedto adjust it I lengthwise. A-lockinut-ll3 on thestudprevents' accidentalrotation thereof? The'studfll is arranged to form an abutment for ashouldervon thehub portion 22 ot the float lever; The adjust a-biiityout the stud enables the descent ot the float lever, yand the quantityot water discharged to be regulatedto any extent desired'.

le represents a thin metal sleeve loosely inserted in the casing lil,and attached at its lower end to the margin of the valve seat 17, thesleeve le being adapted to be withdrawn with the valve seat and valvefrom the casing and to be inserted with said parts into the casing.

There is suliicient space between the eX-` ternal surface of the sleeveand the intei-nal surtaceot the portion of the casing les in which thesleeve is inserted, toY permit water to pass lfrom the inlet branchlS-"to and into the upper end ot the sleeve, as indicated by the arrowsvin Figure l.

To permit the convenient manipulation oi' the sleeve e4,- l provide itwith'fan inwardly projecting earv Ll-, arranged to en`-` gage a lingerinserted in the outer endfot the sleeve.

rlhe `sleeve le sometimes becomes corroded, so that a plumber, repairingthe valve, cannot pull the sleeve out by inserting his ting-er inthesleeve, andin' many cases Vhas t0 remove the entire coclr tronrthetank. rlhe inwardly projecting. ear furnishes a bearing'tor theoperators nger, `whereby he is enabled to exert sulhcient'torce on thetube to turn it, and release it from binding engagement with the casing.The ear also enables a prying tool, such as ya screw-driver, 'to beinserted in the tube 'and used eleetivelyto disengage thelatter from thecasinvfl` lclaim: f
